Distance of time in days

In rails 3 there is distance_of_time_in_words which works fine, but I would like to tweak its ou开发者_运维知识库tput a bit.

The thing is that if the dates are exactly the same it will say "Less Than a day" I would like it to show "Today" instead.

Is that possible?

I wrote a gem called "date-casually" that monkey-patches the Date class with a "casual" method:

Date.today.casual
#=> 'today'

(Date.today + 1).casual
#=> 'tomorrow'

(Date.today - 1).casual
#=> 'yesterday'

Hope it helps:
